roflers `liy F1 as the samel arefforced against .the rotating can between the chucksB C. The. yupper can chuck C or its lshaftC1 -is r oy 110 V tated continuously from the driving shaft E,

upper end ofthe chuck shaft Cl for adjusting the position of the upper chuck'in respect t0 the seaming rollers l1" F1. The double seaming tools or rollers F Fl are mounted on independently movable tool holders or slides F2 F3, and are reciprocated as re uired to force them successively one after-t ie other against the seaming flanges fr aof the can cover X and can body X1 as the can is rotated by the rotary can holding chucks B C by means of independently adjustable vit hardened steel bearing plug f, engaging a similar hardened steel bearing plug f1 on the tool holder slide, and also with a roller f2 which engages the operating cam g on the cam shaft G.

The seeming tools and their holders or slides F2 F3 and their operating levers F4 and the cam shaft G are all mounted on an adjustable tool carriage or slide H, adapted to be moved'in suitable ways A3 on the frame of the machine, to adjust the .machine for operation upon cans of different sizes. or'di'- ameters. rlhe seaming tool operating levers iii-@F5 are adjustably and pivotally connected 4atf'their upper ends to the carriage H by connecting blocks f3 and adjusting screws f4.

The slide or carriage H is adjusted to and from the can holder chucks by means of an adjusting screw H1. It is ixed rigidly in any particular position to which it may be adjust ed by a clamp or set screw h, having` a handle h1. The cam shaft G is intermittently operated or rotated as required from the driving lshaft, E, preferably by a pulley E3 thereon through a belt E4 engaging a pulley K on a 'i shaft K1 carrying a worm liz, ,which engages 45 a worm gear M on a clutch sleeve in. which is `loose on the cam shaft G, and which clutch member M1 is adapted to engage a sliding clutchmember M, having a spring 'in and carried on a sleeve or grooved wheel )i3 which is fixed on the cam shaft G. T he sliding pin or member M2 of the clutch is norn'ially held out of engagement with the toothed clutch member M1 bythe spring m, and is retracted at intervals as required to connect and disconnect the cam shaft from its continuously revolvi'li-e' worm gear by means oi' curved or crescent shaped cam X adapted to fit in and engage a notch m2 in the clutch pin M2, and thus retract the clutch pin from engagement with the clutch member M1 after the cam shaft makes one complete revolution. The movable clutch o Jerating cam or device N is secured to a s iding stem N1 having a spring n for holdingit normally in the groove m3 of the clutchvwheelor sleeve M3. The

vthrough the lever d1.

stem N1 is furnished with a notch n? which is adapted to be engaged by a safctv trip device l on the operating arm Plof :he rock shaft P2 which has an arm P3 ce1-rincer ed by a link I"1 with the treadle D. The 'safetv tri device ,P is mounted to slide on the aim -i L and is furnished with a spring p and withl a pin pl'having a roller 1f which engages'a st tionary cam 3, which operates toretract the safety trip cevice P immediately after the movable cam or wedge N is .withdrawn from the clutch pin by the depression of the treadle D.

The cam shaft G is also furnished with a stop cam Gx which is fixed to the shaft G, and which is provided with a notch G'l which 1 j engages a. roller R on the bent lever R which bratmg levers F* F2, each furnished with a is connected by a link R2 with the treadle D The lever d1 has a slot di for connet tion with the link R2 so that the treadle D may partially raise the lower chuck before the locking lever R1 is disengaged from the stop cam on the rock shaft.

ln operation, the can to be seamed is 'lirst placed on the lower can holder chuck B and then the operator, with his foot on the treadle D, depresses the treadle and thus raises the lower chuck until the can is clnnked against the rotating chuck C and thereby revolved. As the'treadleD is depressed, the locking lever R1 is lifted out of engagement with the stop cam G1, thus permitting the cam shaft G to rotate. The further depression of the treadle D withdraws the movable crescent wedge or cam N from the clutch pin or mem- 1D0 ber M2, and permits the same to engage the toothed clutch member M1, and thereby clutch the cam shaft to the Continuously rotating worm gear M. The slight further depression of the treadle D causes the pin p1 of the safety trip device P to engage the stationary cani p3 and thus release the stem N1 of the clutch disengaging device N, and thus permit its spring n to return it. to position in the cam groove m3 in the wheel or sleeve M3 so that when the cam shaft G completes vils revolution, the sliding clutch )in M2 will be disengaged from the toothed clutch member M1 on the worm gear M, and the further ro tation of the cam shaft stopped.
